This introduces a persisted light/dark appearance setting, maps the desktop shell onto semantic theme tokens, and reworks the highest-traffic chat/settings surfaces so the new dark mode is usable without regressing the original light theme.
The same pass tightens markdown rendering for chat replies by improving inline code, table overflow handling, and safe external-link behavior so dark-mode content stays legible in real conversations.
Constraint: Preserve the existing light theme while adding a user-selectable dark theme in Settings > General
Constraint: Avoid introducing new dependencies for styling or markdown handling
Rejected: Replacing the light palette with a single dual-purpose palette | would risk broad visual regressions across the existing desktop UI
Rejected: Implementing dark mode only for shell chrome | leaves chat markdown, diffs, and permission flows visually broken
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: New desktop UI should use semantic theme variables instead of hard-coded color literals so both themes stay aligned
Tested: bun run lint; bun run test; bun run build; browser review of theme switching, provider/permission states, and chat surfaces
Not-tested: Prototype-style pages with remaining hard-coded colors (scheduled/session control mock surfaces) were not fully normalized in this change
- Add 7 frequency modes (every N min/hours, daily, weekdays, specific days, monthly, custom cron) with progressive disclosure UI
- Add "Run Now" button with confirmation popover and fire-and-forget API
- Add execution logs panel (TaskRunsPanel) with auto-polling and accordion behavior
- Add task edit mode with cron reverse-parsing (parseCron) to populate form
- Add server-side extractAssistantText to store meaningful AI responses instead of raw NDJSON
- Fix session linking: pass --session-id to CLI subprocess so "View conversation" navigates to actual content
- Fix MACRO undefined error by adding --preload to Bun.spawn
- Add confirmation popovers for all destructive actions (run/disable/delete)
- Add DayOfWeekPicker component for specific-days scheduling
- Add cronDescribe utility with i18n support and unit tests
- Display task creation time and last run time
- Add ~50 i18n keys (en/zh) for all new UI elements

Add a lightweight custom i18n system supporting English (default)
and Chinese, with a language switcher in Settings > General.
All 35+ UI components internationalized with ~270 translation keys,
including 189 Chinese spinner verbs and server error code mapping.
The desktop app now keeps the composer stable while turns are active,
reduces low-signal tool noise in the transcript, restores project context
under the composer after session creation, and relies on the CLI's own
permission requests instead of injecting broader desktop-side Bash asks.
This also brings in the supporting desktop app source tree and the server
routes/session metadata needed for git info, filesystem browsing, session
resume, slash commands, and SDK-backed permission bridging so the UI can
operate as a coherent feature instead of a partial patch.
Constraint: Desktop transcript needs to stay usable during long multi-tool sessions without hiding file-change diffs
Constraint: Permission prompts must mirror CLI behavior closely enough that read-only commands do not get desktop-only prompts
Rejected: Keep rendering Read/Bash bodies inline | too noisy and unlike the intended transcript model
Rejected: Commit only the touched desktop files | would leave the newly introduced desktop app incomplete in git history
Confidence: medium
Scope-risk: broad
Reversibility: messy
Directive: Treat non-writing tools as summary-first transcript events; do not re-expand them by default without validating the UX against long sessions
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run test -- --run
Tested: bun test src/server/__tests__/conversations.test.ts
Not-tested: Manual visual regression against the exact screenshots in a live desktop session
Not-tested: Full root TypeScript check (repository still has unrelated extracted-native parse failures)
